The notion of nonmalleable cryptography, an extension of semantically secure cryptography, is defined. Informally, in the context of encryption the additional requirement is that given the ciphertext it is impossible to generate a different ciphertext so that the respective plaintexts are related.

Oberwolfach Reports, 2015
The Oberwolfach workshop Cryptography brought together scientists from cryptography with mathematicians specializing in the algorithmic problems underlying cryptographic security. The goal of the workshop was to stimulate interaction and collaboration that enables a holistic approach to designing cryptography from

This talk is a short overview [This overview is partially based on the paper (Ballet and Rolland, Cryptogr. Commun. 3(4), 189–206, 2011)] on the use of randomness in cryptography. Firstly we give some indications on building and using the randomness and pseudo randomness in a cryptographic context.

Cryptography and factorization methods in cryptography
2018The Security of the RSA cryptosystem depends on the difficulty of finding the prime factors of large integers. Here we explore some of the factorization techniques currently available in cryptography. After giving an overview of cryptography we discuss some of the factorization techniques like Fermat’s factoring, Pollards p-1 method and continued

In this chapter, we discuss the use of cryptography. We go over the history of such tools, from very simple substitution ciphers to the fairly complex electromechanical machines that were used just before the invention of the first modern computing systems, and how they form the basis for many of our modern algorithms.

It appears to be very difficult to give a formal definition of computational security for public-key cryptography. A slightly different notion, called transient-key cryptography, is defined for which a natural definition of security against chosen-plaintext attacks is given.

Publisher Summary Traditionally, cryptography has consisted of any means possible whereby communications may be encrypted and transmitted. This could be as simple as using a language with which the opposition is not familiar. Since the beginning of sentient language, cryptography has been a part of communication. It is as old as language itself.

This chapter discusses how information security is the discipline that provides protection of information from intrusion and accidental or incidental loss. It also provides a framework for the protection of information from unauthorized use, copying, distribution, or destruction of data.
